Reflective Velcro Adjustable Cuff & Integrated external sweat patch

Reflective adjustable cuffs allow for tightening around your gloves for keeping out wind and rain. A sweat absorption patch on the right sleeve helps remove excess perspiration from your face and forehead during long runs.

Bonded Zipper Garage

All zipped pocket closures have an integral bonded zipper garage to protect the slider to avoid any water seeping into the top of the opening.

Reflective Shoulder Seam and Hem

The back hem piping takes advantage of reflective technology for extra visibility in the dark.

Touch Screen Compatible Phone Pocket

With access through the outer chest pocket, the window is fully touch screen compatible, allowing you to control your phone by simply unzipping your jacket halfway. A snug mesh pouch will keep your phone secure while you are running. Cord exits and loops route cables.

Fully Ultrasonic Welded Seams

We’ve replaced conventional stitched and taped seams with barely visible sonic-welded seams for weight reduction and increased strength. Sonic Welding takes advantage of high-frequency microwave technology to fuse petro-chemical based fabrics at a molecular level. With traditional needle and thread applications causing thousands of tiny holes in the jacket seam, sonic welding ensures that all seams are fully fused together helping to avoid seam chafe for greater comfort and allowing freedom of movement.
